Behind the skeleton bridge of the one-minute tourbillon, the 3 Hz (21,600 vph) HMC 804 automatic calibre with three-day power reserve can be seen beating. Powering this movement, the red-gold skeletonised oscillating weight transfers the energy to the barrel via a bi-directional pawl winding system which reduces the time required to fully wind the watch.

This tourbillon features two unique solutions: the state-of-the-art Straumann Double Hairspring which improves the accuracy and isochronism of the movement and the Moser Interchangeable Tourbillon Module which can be assembled and regulated independently of the movement, with a simple "plug-and-play" system, to facilitate servicing.
